Skogsbruket är viktigt för svenskt näringsliv och står för ungefär 20 % av Sveriges totala export. Efterfrågan på virke blir därmed stor vilket resulterar i att avverkning sker ständigt, året om, på all typ av mark under alla olika sorters väderförhållanden. Ett stort problem inom skogsbruket är de markskador som ofta uppstår efter en slutförd avverkning. Markskador ändrar markens textur och egensForestry is important for Swedish industry and accounts for 20% of Sweden’s total export. The endless demand of wood results in logging all year round, but other aspects have to be taken into consideration. The ecology, forest recreation and the outdoor activities that the forest is providing is very important to preserve. A major problem in forestry is the soil damage after a successful harvest.

This thesis analyses the impact of several natural resources on economic growth in the empirically rather poor Sub-Saharan Africa during the time period of 1990-2010. By performing panel regression analyses based on economic and political data from the countries in Sub-Saharan Africa, the conclusion that the production of diamonds promotes economic growth the most could be made. As an example, the

Utrymmet på jordytan håller på att ta slut, vi blir fler och fler och våra städer blir större och större. Istället för att expandera våra städer utåt borde det fokuseras på att göra mer plats i städerna. I en vanlig svensk stad utgörs idag nästan 50 % av vägar och annan transport. Om det mesta av all transport hade kunnat förflyttas ned under marken istället, hade den frigjorda platsen kunnat bli The room for the human race on earth is dwindling. The population is increasing and our cities are expanding every day. Instead of expanding our cities we could focus on creating more room inside our cities. Today close to 50% of the total area of a normal Swedish city consist of transport infrastructure What if we could move most of that 50% down below ground? Imagine all the space it would creat

Ny forskning bidrar till ökad förståelse av allergiska reaktioner Allergi har ökat dramatiskt under de senaste åren. Det är därför högst väsentligt att få ökad kunskap om hur beståndsdelarna i immunförsvaret hos allergiska personer samspelar. Förekomsten av allergi har kommit att öka dramatiskt under de senaste åren och har blivit ett betydande problem för folkhälsan. Allergi drabbar en så stor dThe prevalence of allergic disease is continuing to increase worldwide, and it has even become a major concern in public health. Allergic reactions are developed to otherwise harmless substances and may be both life-threatening as well as discomforting for patients in their daily life. Therefore, a more detailed knowledge about how antibodies interact with allergens and effector cells in allergic

The purpose of our study is to determine the importance of oil exports in relation to GDP in countries located in Sub-Saharan Africa when it comes to promoting economic growth. Due to the fact that oil accounts for approximately 40 percent of the world’s total energy production, and is predicted to do so for at least 45 more years to come, we found this a highly relevant topic to look into. At th

Detta är en artikel om kalkmodifiering av lermorän och är baserad på examensarbetet ”Lime modification of clay till – a case study” (Westesson, 2015). Med kalkmodifiering menas att jordens packningsbarhet förbättras genom inblandning av kalk. Metoden att använda sig av kalk för att förbättra de geotekniska egenskaperna av leror och lermoräner är en nygammal metod och har främst använts till vägproThis report deals with lime modification of clay till. Lime modification means that the compaction properties of the soil are improved by the addition of lime. The report consists of three main parts: 1) Description of the geotechnical properties of clay till and how lime modification affects the properties; 2) Description of the implementation of lime modification and the tests conducted at a con

Denna studie undersöker problematiken med den begränsade kunskap om vad kommunikatörer gör när de arbetar strategiskt med kommunikation. Problematiken innebär att strategisk kommunikation har karaktären av en ”svarta lådan”- teori. Genom en kvalitativ fallstudie av två fallorganisationer inom offentlig sektor har jag genom att göra kvalitativa intervjuer studerat vad kommunikatörer gör när de arbeThis study examines the problem regarding the limited knowledge about what communicator’s do when working strategically with communication. The problem results in strategic communication gaining the characteristics of a “black box”- theory. Through case studies and qualitative interviews in two public organisations I have studied what communicator’s do when working strategically with communication

In recent years, the welfare state has found itself unable to combat issues such as unemployment and poverty, forcing an ever-increasing share of the population to face an increasingly precarious existence. In light of this situation, a growing number of activists and academics have begun to embrace a new means for combating such issues, basic income. Basic income represents a radical departure fr

The encoding-retrieval match has been established as a means to improve memory performance. It has recently been proposed that memory performance is not only explained by the encoding-retrieval match and that the cue overload effect needs to be taken into account when predicting memory performance. In the present study, participants were tested using a cued recall methodology. During a study phase

{swedish} \section*{Sammanfattning} Människans vardagliga liv bygger på transport av olika fordon som drivs med bensin eller diesel. Som bekant för de flesta människor idag bidrar avgaserna till negativa konsekvenser för miljön. Det är mindre känt att dessa avgaser reagerar i atmosfären där de under belysning av solens ultravioletta strålar bildar nya föreningar, så kallade sekundära organiska aerAbstract The behavior of automobile exhaust is well known through combustion science, but the potential health and environmental risks of secondary exhaust particles (created by solar irradiation) and soot are less well understood. Primary pollutants (raw exhaust) react in the atmosphere when irradiated by the Sun creating secondary pollutants (Secondary organic aerosols, SOA). The purpose of this
